Abstract

Electro-Hydraulic servo control is examined as an emerging application for closed-loop control via wireless communication. As wired and wireless Ethernet infrastructures become more common in industry for their simplicity and low cost, their use for control becomes an attractive alternative to existing formal architectures. While some early research has investigated Bluetooth and wireless Ethernet using TCP/IP for wireless control, the applications have typically required little bandwidth and have not focused on servo applications. This work presents results for remote control of a hydraulic servo using UDP communication in an 802.11b peer-to-peer network control loop. A controller node communicates with a remote sensing/actuation node within this framework. A novel timing scheme for communication that does not require clock synchronization is employed and allows for sampling rates up to 200 Hz and near real-time performance. The effect of communication losses and sampling rate on position tracking performance are also investigated.
